Nucleophilic arom. substitution (SnAr) of cyclopentadienyliron-arene complexes with various aliph. or arom. dithiols followed by oxidn. and/or photolysis is presented as a viable route to the prepn. of the corresponding bis(sulfides) and bis(sulfones) in yields of 70-96%. The photochem. reaction of iron complexes I (R = H, alkyl, etc.; X = O, S; Cp = cyclopentadienyl) gave the sulfides II (same R, X).
